Public bug reported: I am looking into enabling EEM with g_ether by module option use_eem=1, and g_ether won't be loaded because it has no EEM support compiled.
Expected: EEM is compiled with g_ether (no such option for g_cdc) so that it can be enabled by use_eem=1.

I remember it was working as expected when I was testing out OTG function. ** Affects: libvirt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864132 Title: g_ether missing eem support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1864132/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
